The 64th Cyberspace Squadron (64 CYS) is a United States Space Force unit under Space Delta 4 responsible for conducting defensive cyberspace operations in support of Space Delta 4's missile warning mission at Buckley Space Force Base, Colorado. It was formed by redesignating the 62nd Cyberspace Squadron to the 64 CYS on 6 January 2023. For many years in the past, as the 460th Space Communications Squadron, it was responsible for base communications support (computers, telephones) for Buckley. Those responsibilities were transferred to an Information Technology Flight in Space Base Delta 2. 460 SCS had a Detachment 1 not located at Buckley.
